Very often in Injera recipes you will see step toward the end of the process, right before cooking that involves cooking some Tef flour with some water and then mixing that into the batter. Can anyone explain what this step is for?
The rough recipe I'm thinking of works like this (also see here:
1) Mix equal parts Tef sourdough starter and Tef flour. Let that ferment for some days.
2) (optional) Mix some more Tef flour into the dough (1 cup) and then wait again.
3) Mix 1/2 cup Tef with 1 cup water in a pot and cook until it thickens, while whising. Let it cool. Then mix it into the batter.
4) Add water slowly to the batter, while mixing, until it is quite thin. Let it ferment again until small bubble form on the surface. Then it's ready to bake.
It's the step #3 that I'm wondering about.
